What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Non-coding uridine-rich small nuclear RNAs (UsnRNAs) have emerged in recent years as effective tools for exon skipping for the treatment of Duchenne muscular dystrophy (DMD), a degenerative muscular genetic disorder. We recently showed the high capacity of a recombinant adeno-associated virus (rAAV)-U7snRNA vector to restore the reading frame of the DMD mRNA in the muscles of DMD dogs. We are now moving toward a phase I/II clinical trial with an rAAV-U7snRNA-E53, carrying an antisense sequence designed to hybridize exon 53 of the human DMD messenger. As observed for genome-editing tools, antisense sequences present a risk of off-target effects, reflecting partial hybridization onto unintended transcripts. To characterize the clinical antisense sequence, we studied its expression and explored the occurrence of its off-target effects in human in vitro models of skeletal muscle and liver. We presented a comprehensive methodology combining RNA sequencing and in silico filtering to analyze off-targets. We showed that U7snRNA-E53 induced the effective exon skipping of the DMD transcript without inducing the notable deregulation of transcripts in human cells, neither at gene expression nor at the mRNA splicing level. Altogether, these results suggest that the use of the rAAV-U7snRNA-E53 vector for exon skipping could be safe in eligible DMD patients.
